Characterization Of Ultralow-Density Silica Aerogels Made From A Condensed Silica Precursor
Published online by Cambridge University Press: 28 February 2011
Abstract
Silica aerogels having densities in the range of 0.003 to 0.05 g/cm3, have been prepared from a condensed silica formulation involving a two-step hydrolysis/condensation process with tetramethoxysilane (TMOS). This work describes the preparation of these unique ultralow-density aerogels, and compares several of their properties with those of aerogels made by a single step, base catalysed process.
